PORTLAND, Ore. (AP)- An attorney for the leader of the occupation at an Oregon wildlife refuge has been hit by a stun gun multiple times and tackled by federal authorities in a courtroom after his client was acquitted.

Ammon Bundy’s defense lawyer Marcus Mumford demanded his client be released immediately after Bundy and six others were found not guilty Thursday. Mumford kept yelling at the judge and wouldn’t calm down, so U.S. marshals used their stun guns on the attorney and then wrestled him to the floor.

Another Bundy lawyer, Morgan Philpot, says Mumford has been arrested.

The judge told Mumford that Bundy would be held because he’s also facing charges in Nevada stemming from a 2014 standoff at his father Cliven Bundy’s ranch.

After Mumford was tackled, the judge cleared the courtroom.

A jury on Thursday exonerated brothers Ammon and Ryan Bundy and five others of conspiring to impede federal workers from their jobs at the Malheur National Wildlife Refuge.

Some of the defendants also were charged with possession of firearms at a federal facility and were acquitted on that count as well.

The standoff began Jan. 2 and lasted nearly six weeks, bringing new attention to a long-running dispute over control of federal lands in the U.S. West.
